Lost Boyfriend Because of Social Anxiety?

My ex and I dated for 2 weeks a couple months ago. It doesn't seem long, but it still hurt when he broke up with me for seemingly no reason. He said we didn't have much in common, which I think was die to my lack of talking. I could text him for hours, but when it came to talk to him in person, i i froze. I was always so anxious. I didn't know what to talk about, or if I would annoy him if I talked at all. I really want to do better at this so I don't scare my next bf away either.
